Aborigines

The earliest inhabitants of central Italy, according to Romanlegends, and supposedly sons of the trees. They lived as nomads, without laws or fixed habitations, and their food was wild fruit. Their name is generally taken to mean 'the original population'. When Aeneas arrived in Latium at the head of the Trojans the Aborigines were ruled by Latinus. Once they were united with the Trojans they formed the Latin race, so called in honor of Latinus.

note: this might (only a guess) be where we get our current term for the native peoples in various parts of the world - esp the more well-known Aborigines of Australia.Gritchka writes: Your guess is correct. They are people who had been there 'ab origine' = 'from the beginning', first applied to pre-Roman Italy, then in modern times to Australia etc.
